Ender's Wand

Ender's Wand is made out of obsidian. Unlike the other Wands, this wand can only be used by Ender. Anyone else who touches it feels a freezing cold shot go through there body.

Ender's Wand can do anything, but it also serves a darker purpose. Sonake hid his soul in it one time, so that it would work as a kind of bomb, and kill Ender. This failed, but cost Ender all of the fingers on his right hand. Temporarily, of course, as he has the Master Gemstones.

It is also capable of accelerating particles up to light-speed, creating deadly lasers and allowing time travel, if used correctly.
